- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
We know that angle between two circlesx2+y2+2g1x+2f1y+c'=0 and x2+y2+2g2x+2f2y+c''=0 is given by cosθ=c1c22-r12-r222r1r2 where, c1c2 is the distance between the centres of the two circles and r1 & r2 are the radius of the circles. Now,…
